CSA B401.4:26

Preface This is the first edition of CSA B401.4, Battery electric vehicle (BEV) maintenance and storage facility code . CSA Group acknowledges that the development of this Code was made possible, in part, by the financial support of Natural Resources Canada. This Code was prepared by the Subcommittee on Battery Electric Vehicle Maintenance and Storage Facility Code, under the jurisdiction of the Technical Committee on Battery Electric Vehicle Transportation and the Strategic Steering Committee on Transportation, and has been formally approved by the Technical Committee. This Code has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope Note: See Annex G for explanatory material. 1.1 Purpose The purpose of this Code is to provide reasonable means to manage the risks associated with the maintenance, repair, and storage of battery electric and hybrid vehicles. Note: See Annex G for explanatory material. 1.2 Inclusions 1.2.1 Vehicle maintenance This Code applies to those portions of battery electric and hybrid vehicle maintenance, depot, and support facilities where vehicles are charged, stored, maintained, and repaired, and to their ancillary areas and systems. If a vehicle has multiple fuels and one of the fuels is compressed hydrogen gas, the requirements of CSA B401.3 will apply. The scope of this Code includes but is not limited to the design, construction, and operation of battery electric and hybrid vehicle maintenance, depot, and support facilities. Elements of electric shock/arc flash control, fire detection and suppression, deflagration, and emergency response and planning are also included, as well as guidance on underground and multi-level storage and charging facilities. Where existing standards cover aspects addressed by this Code (e.g., fire suppression and battery storage/handling), the Code references those works. 1.2.2 Vehicle parking This Code contains information on private parking structures where battery electric and hybrid vehicles are parked or stored, including ancillary areas and systems. Note: See Annex C. 1.2.3 Parking structure requirements For purposes of this Code, private parking structures have the same requirements as minor repair areas. 1.3 Exclusions The scope of this Code does not include a) other fuels used for vehicles; b) natural gas vehicle maintenance facilities, which are covered in CSA B401.1; c) propane vehicle maintenance facilities, which are covered in CSA B401.2; or d) compressed hydrogen vehicle maintenance facilities, which are covered in CSA B401.3. 1.4 Terminology The terms "park" and "store" and all derivatives thereof are used interchangeably in this Code. 1.5 Units of measurement The values given in SI units are the units of record for the purposes of this Code. The values given in parentheses are for information and comparison only. Notes: 1) IEEE/ASTM SI 10 or ISO 80000-1 can be used as a guide when converting non-SI units to SI units. 2) Measurements less than 1 m are shown in millimetres. 3) Measurements of 1 m or more are shown in metres to the nearest 0.1 m. 4) Pressures are rounded to the nearest whole value using traditional rounding conventions. 1.6 Mandatory language In this Code, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Code. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. Note: See Annex G for explanatory material.
